The blinker is the smallest and most common oscillator, found by John Conway in March 1970. It is one of only a handful of known oscillators that is a polyomino, and it is the only known oscillator that is one cell thick (although the pentadecathlon is "almost" one cell thick in that there is a one cell thick pattern that is a grandparent of it).
Blinkers are very commonly formed in a set of four called the traffic light; they can similarly be born in two potential sets of six, the interchanges. There is also a fairly common constellation of four blinkers and two boat-ties.
The blinker is more than one hundred times as common in Achim Flammenkamp's census as the second most common oscillator, the toad. The blinker is also the second most common object on Adam P. Goucher's Catagolue.
